It's Gar. I don't think there are many people who speak fluent Gar-ish.
It would be better to be too rich rather than too lean. Too rich and your bike runs poorly and you foul plugs. Too lean and you blow up your engine. Go for the 80's rather than the 60's, unless you can wait until they get the 70's back in. Or, just order a few sizes individually.
